请教一个正则表达式,匹配所有Html标签外部的指定字符串

比如这样一段代码:

软件地图,软件测1试你好<img src="https://img.gxlcms.com/https://img.gxlcms.com/https://img.gxlcms.com/xxx" alt="a测2试">ASDASD测3试<a href="">a测4试b</a>

匹配:(测\d试)

那么我想要的匹配是

测1试

测3试

而不匹配包含在html标签中的 "测2试" 和 "测4试"
<script> var s='软件地图,软件测1试你好<img src="https://img.gxlcms.com/https://img.gxlcms.com/https://img.gxlcms.com/xxx" alt="a测2试">ASDASD测3试a测4试b' //<[^>]+>?[^<]*> //<(\s|\S)+?> var ary=(s.replace(/<(\s|\S)+?>/igm,'|$|')).split('|$|') for(var i in ary)alert(ary[i]) </script>
